Text Classification is a daunting task because it is difficult to extract the semantics of natural language texts. Many problems must be resolved before natural-language processing techniques can be effectively applied to a large collection of texts. A significant one is to extract semantic information from corpus in plan text. In Vector Space Model, a document is conceptually represented by a vector...
Many interpolation methods were proposed to predict or reconstruct unknown information. However, when the conditional data are quite few or even there are no conditional data, predicted results are often poor. Originally, a method called multiple-point geostatistics (MPS) originated from geostatistical fields and it allows extracting multiple-point structures from training images, after that MPS can...
Multiple-point geostatistics (MPS) simulation originates from geostatistical fields and allows extracting multiple-point structures from training images, after that MPS can copy these structures to the regions to be simulated. Porosity is quite significant to the characterization and prediction of transport properties. To simulate the porosity value, a porosity simulation method using continuous MPS...
Well log analysis is one of the costliest parts of petroleum fields. It has been realized that developing Synthetic well logs can help analyze the reservoir properties in areas where some necessary logs are absent or incomplete, and then reduce costs of companies. During generating synthetic logs, logging time should be used sufficiently for predicting trends and filling some incomplete logs to obtain...
